Description
Summary:In order to solve the disconnecting fault of high-speed shift gear box, this paper uses finite element analysis to study the wear of transmission fork, the transmission of axial force by gear and the cause analysis of gear synchronizer disconnecting fault. A kind of oil film technology is put forward to form oil film between the contact working face of gear sleeve and shifting fork slider, so as to achieve the friction effect of separating the two friction surfaces by liquid. At the same time, the improvement scheme of shift fork material is changed to solve the problem of gearbox fork wear and disconnection. The reliability and stability of the transmission shift mechanism are improved.
